NAB scolds cable companies for downconverting HD locals

We've certainly seen the head honchos give the cable companies a piece oftheir mind before, but this time the carriers are receiving a fairly stiff scolding care of the National Association of Broadcasters. David Rehr made sure to make every moment of his speech segment count, as he ripped cable providers for "downconverting" the signals of local channels in order to boost the bandwidth available to "their own high-definition signals." Mr. Rehr even went so far as to call the process "broadcast discrimination," and we can only presume that certain providers -- such as Time Warner, who has ties to HBO and Comcast, which is strongly linked to Versus / Golf Channel -- are the targets of recent battles. Unsurprisingly, anonymous cable services have reportedly denied the claims of delusion, but how do the actual end-users see it? Let us know folks: is your cable company giving preferential treatment to channels it has vested interest in?
